+Resume an integration with evidence about what changed. The skill now records
+app, contract, runtime and browser inputs, retains still-valid checks and asks
+for fresh verification when those inputs change or dependencies are unknown.
+Interrupted mutations require read-path reconciliation before any retry.
+Execution-capable runners serialize that journal through a stable sidecar OS lock

+
+## What changed
+
+- Removed automatic unpinned guidance-package execution. Official docs are read
+  directly; optional package execution needs an exact reviewed version and approval.
+- Scoped browser work to dedicated test contexts, approved origins and fixtures,
+  with local redacted evidence and explicit untrusted-content boundaries.
+- Added independent effect checks and unchanged-neighbor/invariant assertions.
+- Bounded optional model evals by runner version, data approval, steps, time and spend.
+- Added React remount/Strict Mode and Svelte cleanup acceptance guidance.
+- Defined stable manifest-lock ownership and fail-closed stale-owner recovery;
+  added a two-runner atomic-replacement concurrency regression.
+
+## Compatibility and evidence
+
+This is a backward-compatible skill workflow expansion from v0.5.1. Manifest v4
+remains supported; missing input provenance requires new verification evidence.
+No runtime dependency or TS/JS API changes are introduced. The v0.5.1 browser
+input capability probe remains in place.
+
+Repository tests and the prepared native Chrome fixture check different layers.
+The fixture does not run the full agent skill. Framework recipes are not a
+framework certification; optional model evals have not been run for this release.
+Security text addresses reported audit causes; fresh directory verdicts depend on
+re-indexing and must be checked after shipment. No new PASS badge is claimed.
